HEATING SYSTEM.

Application filed December 16, 1909. Serial No. 533,379.

ToaZZ whom it may concern Be it known that I, EGBERT H. Gone, a

citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Heating Systems, of which the following is a specification.

My invention relates to heating systems in which one or more of the control valves are operated'by a thermostat subjected to the influence both of the hot medium escaping from the system and to the temperature of the external atmosphere. Heating systems of this general character are shown and claimed in my co-pending applications Serial No. 185,122, filed December 14:, 1903, and Serial'No. 24:5,311, filed February 11, 1905; the former application disclosing the inlet valve so controlled, the later application, a system in which both inlet and outlet valves are automatically operated inthe manner described.

The object of the present invention is to provide a novel form of heating apparatus specifically different from those disclosed in the applications above referred to though operating upon the same general plan;the present invention providing a tubular thermostat for controlling the valve or valves which may form a part of the pipe or conduit through which the water of condensation is discharged from the radiating pipes. It is not intended to claim herein the generic inventions shown and described in applications Serial'No. 185,122 and Serial No. 245,311.

The'heating system of my present invention is particularly adapted for use in heating railroad trains.

The invention is illustrated, in a pre-- ferred embodiment, in the accompanying drawings in which- Figure 1 shows a vertical sectional view through the controlling apparatus; and Fig. 2 is an enlarged detail showing in vertical section a modified or alternative arrangement of certain parts.

Like characters of reference indicate the same parts in the several figures of the drawings.

A indicates the floor of a car, which may be, if desired, the usual double floor; B is the inlet pipe leading from the usual train pipe (not shown), which ordinarily extends lengthwise beneath the car and be-- tween which and the pipe B the usual hand Specification of Letters Patent.

posed, if desired, to manually disconnect theheating system of the car from the train pipe; C is the inlet port controlled by the lnlet valve D, which is mounted in an inlet chamber E. From the inlet chamber E pipe F leads to the radiating pipes in the car. The return end of theradiating system connects with the pipe G,.which leads to the discharge chamber H, from which the steam, or other heating medium, goes through the port I to the trap valve chamber J. Extending into the valve chamber J is the discharge or drip pipe K made, for example, of brass or other metal having a relatively high co-efficient. of expansion, the caslng containing the various chambers above described being formed, for example,

of iron, or other metal having a'relatively low co-eflicient of expansion. The lower end of the discharge pipe K is open to the atmosphere andthepipe K is secured to a head L, which in. turn .is connected with the casing containing the trap valve chamber J in any suitable ,inanner, as, for example, by means of iron rods M held in position, by nuts N.

It will be seen that the brass tube or discharge pipe K passes through a [familiar form of-stufiing box 0 and communicates, by means of openings P, with the interior of the trap valve chamber. J. Preferably these openings P are so located as to be on a level-with the bottomof the valve chamber J when the pipe K is contracted, so that any accumulating water of condensation may escape freely from the chamber J through openings P into the pipe K and thence to the atmosphere. If the device, however, is to Work to its'best advantage, care should behad that theopenings P are not so located as to communicate with the external atmosphere in any' position of the tube K when the device is in operation. The

tion are to be used, the port I will be fitted with a nipple R carrying a valve seat 7 and the spider or cap Q will carry avalve 0 so arranged that the expansion of the outlet pipe K under the influence of escaping heating medium will cause the valve q to be seated' on the valve seat 1", but where this feature is not desired, the nipple R and the valve 9 may be .omitted, as shown in the modification appearing in Fig. 2.

- Connected with the cap Q, whatever its form. may be, is a stem S in operative engagement with the forked arm'of a lever T, as, for example, by securing to the stem S the collars s, s. The lever T is mounted on a spindle U interposed in the partition between chambers H and E in a familiar manner,.as.shown,.for example, in my Patent No. 771,628, the spindle U being surrounded by a stufiingbox, if desired, and the arm of the lever '1, which extends into the chamber E, is in operative engagement with the stem V of inlet valve D, as, for example, by forking the end of the lever T so as to surround the stem V and providing the stem V with shoulders 12, 'v.

When so arranged, the inflow of steam from the pipe. B through the valve C, the

chamber E, pipe F to the radiating systern' and backthrough pipe 6*, chambers H and J and out through the thermostatic tube K to the atmosphere, will. fill the system with steam and, expanding the thermostatic tube K, will rock the lever T and close or throttle the inlet valve D, as the case may be. If the device is provided with the outlet valve 9 and valve seat 1*, they will be so arranged withrelation to the other parts that the expansion of the tube K will simultaneously close both the inlet and the outlet valves, whereupon the'tube K, being cxposed'to the external-- atmosphere, will be quickly cooled as soon as the flow of steam or hot water therethrough is shut off and, promptly contracting, will admit more steam, thereby forcing out any accumulated Water of con-- densation, again contracting and throttling the inflowof steam, and so on, thereby keepingthe system atall times filled with steam.

There need be no fear of buckling the tube K by expansion after the inlet valve is seated, because whenever the tube has expanded sufficiently to close the inlet valve, there will be no pressure behindthe body of heating medium in the radiating system and, therefore, no further outflow or further heating of'the tube K.

Copies of this patent may beobtained for In Fig. 2 I have illustrated how the de vice may be modified so as to omit the outlet valve, 'theparts being otherwise substantially the same as above described, the cap Q differing from Q, Fig. 1, in omitting valve 91 Preferably the cap Q is formed with ports J so that there will always be an outlet from. the system.

I claim:

1. The combination with a. heating system comprising a radiator and an inlet valve therefor, of: a thermostat constituting a discharge conduit for said radiator,-of operative connections between said thermostat and said inlet valve, said thermostat being provided with ports so located as to provide free passage for water of condensation from the system when the thermostat is conti-acted but so as to temporarily arrest the discharge of water of condensation when the thermostat is expanded.

2. The combination of aheating system comprising a radiator, an inlet valve therefor, a condensation chamber anda thermostat in operative connection with the inlet valve and consisting of an expansible tubing, serving as a discharge conduit from said condensation chamber and extending into the atmosphere, theouterendof saidtubing being rigidly secured and the inner end thereof extending into said condensation. chamber and provided with discharge ports so arranged as to drain said condensation chamber. when the thermostat is contracted but to be wholly above the lowest'point of said condensation chamber whensaid thermostat is expanded;

3. In a heating system, the combination with a radiator, an inlet valve therefor and five cents each, by addressing the Commissioner of Patents. Washington, D. G.
